LETTER OF TRANSMITTAL. 



United States Department of Agriculture, 



Bureau of Entomology, 

 Washington^ D. 67., February 6^ 1905. 

 Sir: I have the honor to transmit herewith for publication a full 

 account of the bollworm, prepared under my direction by Messrs. 

 A. L. Quaintance and C. T. Brues, special field agents of this Bureau. 

 Mr. Quaintance has been engaged for two 3^ears in investigating the 

 work of this very important and injurious insect, his work having 

 been done mostly in the State of Texas. Mr. Brues assisted him for 

 the larger part of the year 1904. The report is a very careful and 

 complete account of the bollworm, which, although it has previously 

 been written about by many entomologists, has never before received 

 such a full consideration, and I recommend its publication as Bulletin 

 No. 50 of this Bureau. The illustrations submitted are an essential 

 part of the report. 

 Respectfully, 



L. O. Howard, 



Entomologist. 

 Hon. James Wilson, 



Secretary of Agricultttre.
